Freshwater produced from the freshwater generator is used for drinking, cooking, washing, and even running other important machinery which uses freshwater as a cooling medium.
The freshwater generator can be categorized into two types depending upon the principle of operation –
Evaporation method – The evaporation method is one of the processes used in freshwater generators to produce fresh water from seawater. In this method, seawater is heated in a vacuum to a high temperature, causing it to evaporate and form steam earlier than its boiling point. The steam is then passed through a condenser, where it is cooled and converted back into fresh water. This process removes the salt and other impurities from the seawater, leaving behind freshwater that is suitable for drinking, cooking, and other uses.
Reverse Osmosis Method – The RO process involves forcing seawater through a semi-permeable membrane that separates the salt and other impurities from the water molecules.
The evaporation method can be further classified into
